STEPHEN VILSON, OF PHILADELPHIA, PENNSYLVANIA.

BICYCLE.

SPECIFICATION forming part of Letters Patent No. 459,569, datedSeptember 15, 1891.

Application filed December 2, 1890. Serial No. 373,307. (No model.)

To all whom it may concern:

Be it known that I, STEPHEN WILsON, a citizen of the United States ofAmerica, residing at Philadelphia, in the county-of Philadelphia andState of Pennsylvania, have invented certain new and useful Improvementsin Bi cycles, of which the followingis a specification, reference beinghad therein to the accompanying drawings.

My invention has relation to bicycles, and has for its object theprovision of a novel, simple, and eflicient stand or support there forwhen the same are at rest, which forms practically part of the machine,is carried.

thereby when not in operation, and is in the nature of an attachmentwhich is readily adaptable to bicycles-particularly Safety bicycles-ofany character.

My invention consists of the details of construction and in thecombinations of parts, as hereinafter more particularly described andclaimed, and as illustrated in the accompanying drawings, wherein-Figure 1 is a side elevation of a bicycle with my improvements appliedthereto, and Fig. 2 is a rear View of the same. Figs. 3, 4, 5, and 6 areviews of details, enlarged, and Fig. 7 is a transverse sectional view ofthe latter figure. Fig. 8 is a side elevation of part of the bicycleshown in Fig. 1 with a modification of myinvention applied thereto.

Referring to the accompanying drawings, Arepresents a bicycle whoseframe B has therein the upwardly-inclined braces b b and I sustains alsothe handle-bar 6 0C are legs pivotally secured at their inner ends tothe braces through the medium of the adjustable joints D D, which lattercomprise each a round boss 61 with projecting ears d and having asemicircular groove in its rear side for reception of one side of the Abrace, to which it is secured in the desired inclination of the bracesof different machines, through the medium of the screw last mentioned,and having its outer face beveled and provided with acentral boss fprovided with a threaded opening for reception of the set-screw c, whichlatter passes through the inner ends of the legs 0 O and prevents thedislodgment of the latter from their bearings, such ends being formedwith hollow bosses or rings 0 c on opposite sides thereof, the latterencircling the boss f and therewith forming the bearing for said legsand the former receiving the head of said screw, such bosses or rings bytheir contact with the sides of the last-mentioned boss and screwpreventing lateral movement of the legs on their bearings.

G G are chains secured at their lower ends to rings c on the legs 0 Oand at their other ends secured to the ball H, and intermediate theirends passing over the grooved pulleys is,

said pulleys being journaled at an angle corresponding with thedirection of extent of the chains, so as to obviate tendency of thelatter toward slipping off the former on the rod it, which latter passesthrough the sides of the boxes and has nuts 10 on each of its ends,which serve to keep the opposing flanges 70 of the boxes in closerelationand the curved legs 7c in like relation with the mud-guard B ofthe bicycle, such legs having their ends.

bentinwardly for engagement with the edges of said guard, asshown,thereby maintaining the supports for the pulleys in their properposition on said guard.

L is the retainer for the ball H, consisting of a pair ofoppositely-disposed sections having depending legs Z l of a curvaturecorresponding with that of the guard B and having their ends turnedinwardly for engagement with the edges of said guard, having also fiatopposing faces which are maintained in close relation, and the retainerL in position on the mud-guard by the screw-bolt Z passing through saidsections and having thereon the nut Z The upper portions of saidsections are formed with curves 1 therein, which form an opening of lessdiameter than that of the ball H, preventing the passage of the lattertherethrough when in engagement with the rear of the retainer, formaintaining the legs 0 O in their lifted positions, while theextremities thereof flare outwardly, facilitating the entrance of thechains to the opening when the ball is being placed in this position.The retainer L and the supports for the pulleys are, as shown, withineasy reach of the rider, and the ball, whose path lies between them, isalso within such easy reach without necessitating dismounting from thesaddle. When the ball H is disengaged from retainer L and allowed topass to the pulley-supports, where it is limited against furthermovement, the legs C C, which are curved outwardly near their upper orinner ends, so as to afford clearance for the steps 00, and the otherparts will assume the positions shown by the dotted lines in Fig. 1 andfull lines in Fig. 2, where, as will be observed, the lower or free endsof said legs are divergent only to such extent as to prevent theoverbalancing or tipping of the machine to either side when the rider isthereon. The points 0 secured in the ends last mentioned, preventingslipping, are arranged by the bending of their shanks, which arepreferably screwed into such ends so that they will stand vertically,such divergence being caused by the riding of the inner ends of the legsfrom the thinnest to the thicker parts of the cams, and can beregulated, according to the inclination of the braces or for any otherpurpose, by turning the cam in either direction when the screwf isloosened. On the other hand, when the legs are drawn up into theposition shown in full lines in Fig. 1 by drawing the ball from contactwith the boxes 10 to engagement with the retainer L, thereby drawing thechains over the pulleys, the inner ends aforesaid ride from the thickerto the thin portion of the cams, allowing the legs to swing inwardly intheir upward movement and rest in close relation with the rear wheel ofthe machine and in alignment with the frame of the latter, where it isclear of obstructions. Obviously when the legs 0 O are in the positionshown in full line in Fig. 2 unless means are employed for preventingthe going forward of the machine such legs will be ineffective to attainthe result desired unless the machine is brought to a dead-stop andproperly balanced before placing the legs in such position. Thereforeabrake-lock must be employed, which look is preferably of the charactershown in Figs. 1 and 3, although any other form of brake-lock may beemployed for obviating the necessity of keeping the hand always on thebrake-lever, where M is a swinging lever hinged or pivoted 011 the pin min the lugs n of the strap N, such strap being secured rigidly to thehandle-bar b? by the screw 47. passing through the lugs n and operatingto clamp the same thereon, the up per half of this strap being hinged onthe pin m, so as to allow of the strap being placed on the handle-barfrom the side thereof. The lower end of lever M is formed into a hook m,with an inclined or beveled end m depending therefrom, the end of saidhook eX- tending inwardly beyond the vertical plane of the pin m and theplane of the brake-lever lever is drawn toward the handle-bar it willstrike the beveled end m and force the hook m outwardly until it clearsthe latter, when such hook will swing inwardly again under the lever O,which completes the locking operation, which therefore is accomplishedautomatically. WVhen it is desired to unlock the brake-lever, the latteris drawn upwardly slightly, so as to clear the hook, and the latter isthen drawn from the path of the lever O by pressing inwardly the upperend m of the lever M.

In lieu of the ball H and retainer L the lever P, which is shown in Fig.8, may be employed, the same being pivoted on a bracket or fork cl onthe mud-guard of the machine, having the chains attached thereto at apoint below its pivot, so as to prevent accidental dropping of the legs0 O, as shown at p, and being provided with a stop 19 for preventing thehandle of thelever from coming into close relation with said mud-guardand rendering it more difficult to grasp, when in the position shown bythe dotted lines in the figure lastmentioned. Furthermore, instead ofsecur ing the joints D D to the braces b b, it may be found desirable tosecure them in align ment with the axis of the rear wheel of themachine, the same being possible without necessitating a departure fromthe spirit of my invention.

lVhatI claim as my invention is as follows:

1. In a bicycle,thecombination'ofthe frame, the joints D D, secured onthe latter, and a leg on each side of the frame and. pivotally securedat their inner ends on the cams F of said joints, substantially asspecified.
